Cutting off my neighbor -

I’m 33 weeks pregnant and extremely tired. I’ve been trying my best to rest, and spend time with my 4yo as well as prepare for the arrival of baby. My neighbor who seems to must be bored out of her freaking mind, keeps bothering me and coming over with her two wild children. I’ve tried to avoid them, giving excuses but they end up on my doorstep and inviting themselves over. Now, texts me and says her dog sitter just fell through, could I help to feed her dog 3 times. I thought, sure why not, I’ll be home anyways and I want to be nice. After I said yes, she bamboozled and said “feed, then take the dog out back to use the potty, 3x today and the next day” I’m like wtf. I’m so over it, I’m getting anxious as to whether the dog is friendly because I have a huge belly and I’m afraid the dog would attack since I’m unfamiliar. But I’m assuming they know their dog, and they know I’m pregnant, they wouldn’t ask if they knew their dog would harm me. But seriously, I’m done. I’m not used to such an intrusive neighbor, I just want to coexist, occasionally say hi when we see each other but that’s it. I know she’s being too friendly, but damn. Lol
